Abstract: Objective To explore effects of long-term multiple pesticide exposure in the greenhouse on the birth quality of newborns. Methods The delivery women were randomly selected from the department of obstetrics and gynecology of 3 hospitals in Weifang during the period from March 2010 to December 2014.Among them,439 women farmers who had been continually working more than two years in the greenhouse during progestation and gestation with their 431 newborns were selected as exposure group;and 152 delivery women who didn't contact pesticide and engage in greenhouse with their 151 newborns were selected as control group.Informations about women farmers who were engaged in vegetable greenhouses were collected through questionnaire survey and look up data,which included the situation of pesticide exposure,the general situation of maternal and so on.The data were acquired about birth quality of newborns through field investigation and the conventional analysis of historical data.According to the cumulative pesticide exposure index,the exposure group was divided into low,media and high exposure group. Results About the newborns,sex ratio was 1.09∶1,gestational age (39.46±0.28) weeks,birth weight (3.06±0.86)kg.All morphological indexes such as height,head circumference,chest circumference were within the normal range.About the Agpar score,the rate of 1 minute score >7 points was 89.52%,the 5 minutes score > 7 points accounted for 92.61%,10 minutes score >7 points was 95.36%.There were 103 sub-health newborns,accounted for 17.70% of the newborns,and 7 birth defects accounted for 1.89%.The differences of gestational age,birth weight,body length,Agpar score and the sub-health newborns were statistically significant among the three exposed groups.Altogether,there were statistically significant between the high exposure group and the control group. Conclusion The pesticide exposure in the greenhouse can cause reproductive health damage such as premature birth,low birth weight,reduce the body length and Agpar score; and it may also increase the risk of congenital malformation of offspring.
